TITLE

cURL and libcurl In Cookie Vulnerability set

DESCRIPTION

cURL and libcurl before 7.38.0 does not properly handle IP addresses in cookie domain names, which allows remote attackers to set cookies for or send arbitrary cookies to certain sites, as demonstrated by a site at 192.168.0.1 setting cookies for a site at 127.168.0.1. cURL/libcURL is prone to a remote security-bypass vulnerability. An attacker can leverage this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. cURL/libcURL 7.1 through 7.37.1 are vulnerable. Both Haxx curl and libcurl are products of the Swedish company Haxx. libcurl is a free, open source client-side URL transfer library. ============================================================================ Ubuntu Security Notice USN-2346-1 September 15, 2014 curl vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS Summary: Several security issues were fixed in curl. (CVE-2014-3620) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: libcurl3 7.35.0-1ubuntu2.1 libcurl3-gnutls 7.35.0-1ubuntu2.1 libcurl3-nss 7.35.0-1ubuntu2.1 Ubuntu 12.04 LTS: libcurl3 7.22.0-3ubuntu4.10 libcurl3-gnutls 7.22.0-3ubuntu4.10 libcurl3-nss 7.22.0-3ubuntu4.10 Ubuntu 10.04 LTS: libcurl3 7.19.7-1ubuntu1.9 libcurl3-gnutls 7.19.7-1ubuntu1.9 In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: curl security, bug fix, and enhancement update Advisory ID: RHSA-2015:2159-06 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2159.html Issue date: 2015-11-19 CVE Names: CVE-2014-3613 CVE-2014-3707 CVE-2014-8150 CVE-2015-3143 CVE-2015-3148 ===================================================================== 1. Summary: Updated curl packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit. (CVE-2014-3613) A flaw was found in the way the libcurl library performed the duplication of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's duplicate could cause the application to crash or disclose a portion of its memory. (CVE-2014-3707) It was discovered that the libcurl library failed to properly handle URLs with embedded end-of-line characters. An attacker able to make an application using libcurl access a specially crafted URL via an HTTP proxy could use this flaw to inject additional headers to the request or construct additional requests. (CVE-2014-8150) It was discovered that libcurl implemented aspects of the NTLM and Negotatiate authentication incorrectly. If an application uses libcurl and the affected mechanisms in a specifc way, certain requests to a previously NTLM-authenticated server could appears as sent by the wrong authenticated user. Additionally, the initial set of credentials for HTTP Negotiate-authenticated requests could be reused in subsequent requests, although a different set of credentials was specified. (CVE-2015-3143, CVE-2015-3148) Red Hat would like to thank the cURL project for reporting these issues. Bug fixes: * An out-of-protocol fallback to SSL 3.0 was available with libcurl. Attackers could abuse the fallback to force downgrade of the SSL version. The fallback has been removed from libcurl. Users requiring this functionality can explicitly enable SSL 3.0 through the libcurl API. (BZ#1154060) * TLS 1.1 and TLS 1.2 are no longer disabled by default in libcurl. You can explicitly disable them through the libcurl API. (BZ#1170339) * FTP operations such as downloading files took a significantly long time to complete. Now, the FTP implementation in libcurl correctly sets blocking direction and estimated timeout for connections, resulting in faster FTP transfers. (BZ#1218272) Enhancements: * With the updated packages, it is possible to explicitly enable or disable new Advanced Encryption Standard (AES) cipher suites to be used for the TLS protocol. (BZ#1066065) * The libcurl library did not implement a non-blocking SSL handshake, which negatively affected performance of applications based on the libcurl multi API. The non-blocking SSL handshake has been implemented in libcurl, and the libcurl multi API now immediately returns the control back to the application whenever it cannot read or write data from or to the underlying network socket. (BZ#1091429) * The libcurl library used an unnecessarily long blocking delay for actions with no active file descriptors, even for short operations. Some actions, such as resolving a host name using /etc/hosts, took a long time to complete. The blocking code in libcurl has been modified so that the initial delay is short and gradually increases until an event occurs. (BZ#1130239) All curl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. 4.

For this problem to trigger, the client application must use the numerical IP address in the URL to access the site (CVE-2014-3613). Symeon Paraschoudis discovered that the curl_easy_duphandle() function in cURL has a bug that can lead to libcurl eventually sending off sensitive data that was not intended for sending, while performing a HTTP POST operation. This bug requires CURLOPT_COPYPOSTFIELDS and curl_easy_duphandle() to be used in that order, and then the duplicate handle must be used to perform the HTTP POST. The curl command line tool is not affected by this problem as it does not use this sequence (CVE-2014-3707). When libcurl sends a request to a server via a HTTP proxy, it copies the entire URL into the request and sends if off. If the given URL contains line feeds and carriage returns those will be sent along to the proxy too, which allows the program to for example send a separate HTTP request injected embedded in the URL (CVE-2014-8150). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0015 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0138 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0139 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3613 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3620 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3707 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8150 http://advisories.mageia.org/MGASA-2014-0153.html http://advisories.mageia.org/MGASA-2014-0385.html http://advisories.mageia.org/MGASA-2014-0444.html http://advisories.mageia.org/MGASA-2015-0020.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 498d59be3a6a4ace215c0d98fb4abede mbs2/x86_64/curl-7.34.0-3.1.mbs2.x86_64.rpm 75a821b73a75ca34f1747a0f7479267f mbs2/x86_64/curl-examples-7.34.0-3.1.mbs2.noarch.rpm f5d3aad5f0fd9db68b87c648aaabbb4a mbs2/x86_64/lib64curl4-7.34.0-3.1.mbs2.x86_64.rpm 4f356a2c97f9f64124b4e8ebe307826a mbs2/x86_64/lib64curl-devel-7.34.0-3.1.mbs2.x86_64.rpm d010a357d76a8eb967c7c52f92fb35ae mbs2/SRPMS/curl-7.34.0-3.1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
